T at whom it may concern:

Be it know-n that I, JOHN JAKoB BURK- HARDT, a citizen of the United States, residing at Tiftin, in the county of Seneca and State of Ohio, haveinvented a new and useful Glass- Working Machine, of which the followingis a specification.

The invention relates to improvements in glass-working machines.

One object of the present invention is to improve the construction of machines for working glass and to provide a simple and comparatively inexpensive one capable of enablinga mold to be opened and closed by the operator and adapted after the glass is removed from the mold and by the same operation to discharge a quantity of Water upon the mold for the purpose of cooling the same.

Another object of the invention is to collect the water after it has been discharged upon the mold and to enable it to be reused, thereby reducing the consumption of water to a minimum and preventing the same from escaping.

Another object of the invention is to enable the articles to be readily removed from the blow-tube and to collect the same and enable them to be readily discharged into a suitable receptacle.

Furthermore, the invention has for its object to provide a machine which will be adapted to be readily adjusted for operating molds of different sizes.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side elevation, partly in section, of a machine constructed in accordance with this invention. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal sectional view. Fig. 4 is a horizontal sectional view on line 4 4 of Fig. 3. Fig. 5 is a detail perspective view illustrating the manner of supporting the mold. Figs. 6 and 7 are detail views of pivoted cradles. Fig. 8 is a detail perspective view of the pump-barrel and its diverging troughs.

Like numerals of reference designate corresponding parts in all the figures of the drawlugs.

1 designates a supporting-frame provided stands, and located beneath the platform is a tank 3, adapted to contain water for cooling a mold 4. The mold 4, which is of the usual tions connected at the back by a vertical pintle 5, which passes through eyes of the sections of the mold and which has its lower end journaled in a suitable bearing 6 of an adjnstable support 7. The support 7 consists of a horizontal shelf and a pair of upwardly-extending arms 8, located in vertical grooves or justably secured to the same by means of a transverse pin 11, passing through perforations of the upper ends of the .arms 8 and adapted to be arranged in any one of a series of perforations 12, formed in the central portion of the standard or upright 10. The standard or upright 10 is provided at its top with a recess 13, and it has a slot or opening 14 at its front, communicating with the recess and adapted to receive a neck 15 of a bearing block 16, which is grooved at opposite sides to form the neck 15. The inner. portion of the bearing-block fits in the recess of the upright or standard, and the projecting front or outer portion is provided at its lower face with a socket 17 for the reception of the upper end of the pintle' of the mold 4. By adjusting the support 7 vertically the machine may be arrangedto receive a mold of any size.

The sides of the mold are provided at their outer faces in advance of the pintle with pivots 18, detachably engaging eyes 19 of connecting-rods 20, which are pivoted at their inner or rear ends to a pair of levers 21, and the latter are fuloru med at their lower ends 22 on a bottom frame 23 and are adapted to oscillate backward and forward from the position shown in Fig. 1 to that illustrated in Fig. 3. The upper ends of the supporting-levers 21 are connected by links 24 with a transverse bar or piece 25,which is also connected vers 26. The ends of the transverse bar or piece 25 are provided with projecting pivots 27,which extend through slots 28 of the lower ends of the links 24, as clearly shown in Fig. 3 of the accompanying drawings. The levers 26, which are fulcrumed between their ends recesses 9 of a vertical standard 10 and ad- 1 with a platform 2, upon which the operator construction, is composed of two hinged secwith the rear ends of a pair of oscillating lerod or plunger 33.

' barrel 34.

on a standard or support 29, are disposed approximately horizontally when they are near the center of their movement, and their arms are adapted to swing upward and downward. They are provided between their ends with eyes for the reception of a pivot 30, which is adapted to be arranged in any one ofa series of perforations 31 of the support 29, and the front ends of the levers 26 are connected by rods or bars 30 with a treadle or plate 32, secured to the upper end of a vertical movable The rod or plunger 33 is arranged within a cylinder or tube 34 and it carries a valved plunger-head 35 and is adapted on the upstroke to elevate a quantity of water which is discharged through an opening 36 at the upper portion of the cylinder or The cylinder or barrel and the plunger constitute a pump, and the openings 36 communicate with a pair of diverging troughs 37, extending outward and located over the sections of the mold when the latter is open and provided with perforations 38, through which the water is discharged and caused to flow over the sections of the mold to cool the same. The lower ends of the connecting rods or bars, which extend" from the foot-plate or treadle to the front ends of the oscillating levers 26, are provided with perforations 39, arranged at intervals and adapted to receive pivots 40 to vary the connection between the levers and the plunger of the pumping device to regulate the quantity of water and the depth of the plunger in the tank 3. When the treadle or foot-plate is depressed by the foot of the operator, the

plunger is forced downward to the position shown in Fig. 3, and the levers 26 are oscillated to swing the transverse connecting bar or piece upward, and motion is communicated through the slotted links to the oscillating levers 21, which spring forward and close the sections of the mold. As soon as the operator removes his foot from the treadle or footplate the levers 26 are swung in the opposite direction by means of a weight 41, secured to the transverse connecting bar or piece 25, near the center thereof, preferably by means ofahook 42, as illustrated in Fig. 3; but any other suitable means may be employed for weighting the transverse connecting-piece 25. This reverse movement of the levers 26 swings the levers 21. rearward and opens the sections of the mold, and the upward move-' ment of the plunger carries a quantity of water upward and causes the same to be discharged over the sections of the mold. The supporting-frame, which is arranged at the bottom of the tank, may be of any suitable construction, and the upright or standard 10 and the support 29 are suitably secured to the same, and the pump cylinder or bar-rel is preferably mounted on the upright or standard 10.

The supporting-frame l, which for-ms the framework of the machine, is provided in advance of the platform with standards or. up-

rights 44, located at opposite sides of the main frame and connected at their upper ends by a horizontal top piece 45, which is provided. with an opening 46, having a flaring mouth 47 and adapted to receive the lower end of the blow pipe or tube and the glass to enable the article to be readily broken off. The article after it has been broken off from the pipe or tube of the operatorfalls into a piv oted cradle 48, mounted between the standards or uprights 44, The molded article is broken off from the tube by drawing the latter upward through the opening 46, and when the molded article falls into the pivoted cradle 48 it overbalances the same and automatically dumps itself into a tray 49. The eradle 48, which is provided with a curved bottom, has sides and is pivoted near its rear end, the front portion of the cradle being counterbalanced by a weight 50 to hold it in position to receive the molded article. The molded article rolls down the inclined bottom, and as it reaches the front portion of the pivoted cradle the latter swings downward, and the article is deposited in the tray 49 without danger of breaking it. The era dle is provided with a pivot rod 51, which is adapted to be arranged in any one of a series of open bearings 52 to arrange it the proper distance from the opening 46 to suit the size of the article to be discharged into the tray. The tray is pivotally mounted in advance of its center on suitable posts or supports 53, and its rear end is supported by horizontal projections or pins '56, extending from the outer faces of the standards 44 and arranged to receive the sides of the tray, which are extended beyond the rear edge of the bottom, as clearly illustrated in Fig. 3 of the accompanying drawings. The tray is provided with an inclined arm 57, terminating at its upper end in a grip'or handle 58 and adapted to be readily grasped to tilt the tray for discharging the-contentsthereof into a wagon or other vehicle for collecting the articles. The "standards or uprights 44 are also provided with open bearings 69, adapted to receive a pintle-rod of a cradle 71, designed to be substituted for the cradle 48 and adapted to'receive large articles. The open bearings 69 permit the cradle 71 to be adjusted vertically and arranged at different elevations on the standards or uprights 44, and the said cradle 71 is provided at its back with a grip or handle 72 to enable it to be operated by hand. v v

It will be seen that the machine is simple and comparatively inexpensive in construction, that it is capable of enabling a mold to be opened and closed and a quantity of water,

discharged upon the sectionsthereo'f by the foot of the operator, and that the molded arcut that the machine is adapted to operate I molds of various sizes and that it may be readily adjusted to receive the same, and that it will enable a glass-blower to operate more rapidly, maintain the molds in proper condition, and deliver the completed article to the tray without the aid of mold boys.
